Hi
It does look good for Penshaw.
George and Maria and family are still in Harraton in 1851, and that's where William, Elizabeth. and son George Dawson are too.
Looking for Robert and Mary Galloway's daughter, Elizabeth Charlotte.
Is there something odd here?
Elizabeth Charlotte Galloway was registered in Sep qtr 1889, Gateshead.
In 1891 census, with her parents, she is age 1, born Gateshead.
No obvious death for her before the 1901 census, so she should be around, like her brother Robert Ernest.
There is in Gateshead
Charlotte Galloway, Step Daur, 11, born Durham Gateshead.
https://www.familysearch.org/ark:/61903/1:1:XSHV-37YShe is with James Poole, Widower, 53, Labourer Steel Works. He's born in Shropshire.
He has three children, youngest Lydia, 12, born Gateshead.
So in 1891 in Gateshead, James Poole is married to Annabella, 37
https://www.familysearch.org/ark:/61903/1:1:WJ3F-ZMMDeath in Gateshead, Sep qtr 1891, of Annabell Poole, age 39.
Marriages, June qtr 1896, Gateshead 10a 1395
Galloway, Mary
Poole, James
The other two names on page 1395 are Thomas E H Bell, and Mary Ann McLeod.
Common name though Bell is, it seems they can be paired off, living in Gateshead in 1901, and Newcastle in 1911, with daughters Agnes, Norah, Hilda.
